Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings
The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.
Kriskommunikation i ett senmodernt samhälle ? exemplet Svenska Röda Korset
The purpose of this study is to examine how an organization communicates during a crisis and how a crisis can affect an organization's reputation/credibility in late modernity. The focus is on how the Swedish Red Cross handled crises from summer 2009 until spring 2010, and how the organization's reputation/credibility was affected by the fact that society has changed. The methodology used is a quantitative and qualitative text analysis. The results show that crises affect organizations, how much depends on how open they appear to be and how much credibility they have with them when the crisis begins. Getting to know the late modern society, to understand how it works, can bring benefits to an organization during a crisis.
Modellering av hydrauliskt aktuatorsystem
This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.
Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
En kvinnas mansbilder : kontextualiseringar av Maria Fribergs konst
The aim of this essay is to debate the narrow contextualization of the works of Swedish artist Maria Friberg, in which she is interpreted as a female, feminist artist engaged in masculinity studies. Art reviews and exhibition catalogues regarding a great part of Friberg?s work have formed the core body of information in this study, selecting the more recent works entitled Still lives (2003- ) as the main focus. These show a change in Friberg?s artistic expression.Subjects concerning group belonging, identity and existential questions have always been present in Maria Friberg?s art, but they are more clearly expressed in her latest works.

Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
1600-talets urvalsprocesser för tryckta verk : Produktion och distribution av böcker och dissertationer i Stockholm och Uppsala
During the 17th century the production and distribution of printed works increased in Stockholm and Uppsala. However, all works that the publisher wanted to print, did not reach the reader. This thesis aimed to show when, where and how printed books and dissertations did not reach the reader. To achieve this aim, aspects of several well known models showing systems of book production and distribution were combined and adapted to suit Swedish conditions in the 17th century. This combined model focused on processes of selection and was presented and used as a theoretical approach.
Hopfällbar hjullösning
In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.
En kommunikations hemlighet : En studie om externkommunikation inom en ideell organisation
My essey concern the non-profitable organization Ung företagsamhet and their extenal communication with collaborators. I have done three intervjues with three of Ung företagsamhets 24 district in Sweden, and these are Kalmar, Jönköping and Skåne. My qustions conserns their rethoric and strategic communications channales, and the focus lies in their external communications with collaborators. I have also made a secondary data analysis about their media coverage and seen how they consciously works with it.Ung Företagsamhet is a non-profit organization that need good partnerships in order to survive financially. My analysis shows that the three different regions works variously with their external communication.
Konstruktionstudie av en ångexpander
This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.
Bland gudar och krigare : asatro, ideologi och mansidealet i nationalromantikens konst
This essay is about how the aesir are used as an ideal image of the original Nordic aspects and as a symbol of heroism and pure strength. The main subject of this essay is to look at how this ideal of masculinity is represented in the art produced during the era of romantic nationalism. The choice of focusing on this era in particular is made due to the fact that it was during this time that the modern images of the aesir and the Vikings were made. The purpose of this study is to examine how the ideal of masculinity reflects upon the artistic interpretations of the Norse mythology in a selected group of art work produced during the 1800?s.
Modellering av en panna med rörlig rost :
The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
Att bibehålla bestående kundrelationer : Hur kan inre och yttre faktorer påverka dessa?
This thesis treats how accountancy companies works to maintain customer relations. This is getting more important in the accounting business because there are several inner and outer factors available that may affect customer relations in this business area. The main question with the thesis is: How works accountancy companies with keeping customers?The purpose with the research was to investigate and identify which inner and outer factors that may be important from a company perspective to keep customers. Another purpose was to investigate if there existed any differences between the companies in how they are handling different factors like for example a law change and how it could affect customer relations.
Barn med autism : En studie i hur skolarbetet kring barn med autism ser ut
This essay is about how working with children with autism works with the laws and regulations that fall under the Compulsory School Ordinance and Lgr11 (Compulsory for primary school, preschool classes and kindergarten). The aim of this work was to examine various educators thoughts, experiences and practices related to children with autism in primary school. The study is based on three questions: what kind of rights regarding support do children with autism have in the Swedish primary school, according to the primary regulation and Lgr11? How do the selected primary schools work with the support of children with the diagnosis of autism? And how well does the affected educator?s think that the support works?To answer these questions, four qualitative interviews with various educators, were made. My results show that all four educators believe that inclusive labor of children with autism is a good thing for everyone, as long as it is done properly and with the right order, so that the child with autism gets the opportunity to be part of a social group.
